Defining mesoscopic length scales for deformed nanostructures requires a close coupling of theory and experiment. One approach to this is to mechanically probe single crystal nanospheres of the same size that can be evaluated computationally. This involves ...
A combined analytical and FEM method for prediction of the no-load voltage waveform of laminated salient pole synchronous generators is presented in this article. Very precise prediction of the no-load voltage, including saturation effects as well as the e ...
During the turn-on process insulated gate bipolar transistors (IGBTs) traverse a quasi-saturation region from the off.state to the on-state (saturation). The additional voltage drop due to the quasi.saturation of the junction hardly depends on the DC-link ...
Electromagnetic transformers have become obstacles to progress power supply miniaturization. Thus, piezoelectric transformers, which are more compact, immune to magnetic field and that present a high galvanic insulation, become more and more an alternative ...
Nonlinear devices, such as power electronics converters, inject harmonic currents in the AC system and increase overall reactive power demanded by the equivalent load. Also, the number of sensitive loads that require ideal sinusoidal supply voltages for th ...

A filter-press-type Al/O2 battery with bipolar assembly of the electrodes was developed. The current-voltage curves and power output of monopolar and of bipolar batteries contg. one to four cells were measured in alk. (4M NaOH and 7.5M KOH) and acidic (3M ...
A DC-DC converter is proposed with new modulation schemes for a voltage-controlled output. The DC-DC converter is designed for a reversible current in order to feed DC current motors or four quadrant converters, which need a galvanic separation from a DC s ...
This paper presents a combined analytical and FEM method for prediction of the no-load voltage waveform of laminated salient-pole synchronous generators. The described method takes into account saturation effects as well as the damper bar currents due to t ...
The invention describes a method for electrochem. producing the peroxodisulfuric acid and peroxodisulfates by electrochem. oxidn. of sulfuric acid. The process was carried using on an anode which, preferably, was not completely prepolarized and which was c ...
